Steel wire specific weight: weight of 1 linear meter
One of the most demanded forms of rolled metal is wire: a long product with a diameter from fractions of a millimeter to several centimeters. This strong and practical product has a low cost and a very wide range of use; it can be found almost everywhere, from wiring, nails and mesh to decorative products. It is successfully used in industry, agriculture, medicine and other fields, and can be an independent product or a blank for further processing.
Wire shapes range from round to oval, square, triangular and even hexagonal. Various metals and alloys are used for wire production. Most often it is carbon steel, as well as copper, titanium, nickel, aluminum, zinc and other metals. Polymetallic wires are also produced.
Types of wire
Steel wire is the most widely used. It is classified by area of use and characteristic features:
- general-purpose wire, material - low-carbon steel, used for making nails;
- stainless wire, material - heat-resistant and corrosion-resistant alloy, used in fastener production;
- galvanized wire, material - galvanized steel, used for making springs, cables, electrodes and so on; it is resistant to environmental exposure; varieties include rope wire for severe operating conditions and spring wire with high elasticity and strength;
- reinforcing wire has a special surface shape that provides stronger adhesion to concrete;
- binding wire, material - low-carbon steel; its feature is high ductility; it is produced by passing through a drawing mill.
Steel wire weight calculations
Wire thickness can vary greatly. Knowing its diameter and length, the weight of steel wire can be easily calculated. Convenient online calculators can be used for faster mass calculation.
To find out how many kilograms are in 1 meter of wire, use the following formula:
m = S * g * 1
where m is the weight of 1 linear meter of wire, kg;
S is the cross-sectional area, mm2; S = 3.14 * d * d / 4, where d is the wire diameter;
g is the metal density.
This formula is suitable for calculating the weight not only of steel wire, but also of wire made from any other metals.
Round wire rod is used more often than all other types of wire. It is produced by hot rolling followed by cooling. Wire rod is a blank for many products, such as nails, staples, studs, bolts, meshes and so on. It is produced according to GOST and must meet certain parameters.
| Wire diameter, mm | Weight of 1 linear meter, kg | Meters in one tonne of wire |
|---|---|---|
| 5 | 0.154 | 6493 |
| 5.5 | 0.186 | 5376 |
| 6 | 0.222 | 4504 |
| 6.3 | 0.245 | 4081 |
| 6.5 | 0.26 | 3846 |
| 8 | 0.395 | 2531 |
| 9 | 0.499 | 2004 |
When making calculations and buying steel wire, note that according to GOST a “minus” deviation in parameters is allowed, meaning the real diameter and weight values will be slightly lower than the theoretical ones.
Frequently Asked Questions
Can the density of steel wire be used for precise calculations?
The density and weight values for steel wire in this article are reference values. They are suitable for preliminary estimates, but design, construction, production and other critical calculations should be checked against standards, material datasheets or measurement results.
Why can the actual weight of steel wire differ from the table?
The actual weight of steel wire depends on composition, moisture, temperature, porosity, fraction size, material grade and measurement conditions. Because of this, real values may differ from the average table data.
How do you calculate the mass of steel wire from density?
For an approximate calculation, use the formula: mass = density × volume. If the density of steel wire is given in kg/m³ and the volume is in m³, the result will be in kilograms.
